泡菜中两株乳酸菌的分离鉴定及其混合培养初探
Isolation and Identification of Two Strains of Lactic Acid Bacteria from Kraut and Preliminary Study on Their Co-culture
摘要
Abstract
Two strains of acidophilic Lactobacillus bacteria BL1 and BL2 were isolated from Kraut. After fermented for 24 hours in MRS medium, the two strains could make the pH value of the fermenting liquid below 3.5. Both bacteria were identified to be Lactobacillus sp. based on the morphological and physical characters. The 16S rDNA genes of both bacteria were cloned by PCR, and their accession number in NCBI were HM800503 and HM800504 respectively. The nucleotide sequences of 16S rDNA of BL1 and BL2 had the highest identity of 99% with L. pewlens and L. rhamnosus, respectively. The co - culture results showed that they could activate the growth of each other.关键词
